Beyond Linux From Scratch - Version 6.1

Preface

Who Would Want to Read this Book

This book is mainly aimed at those who have built a system based on
the LFS book. It will also be useful for those who are using other
distributions, but for one reason or another want to manually build
software and are in need of some assistance. BLFS can be used to
create a range of diverse systems and so the target audience is
probably nearly as wide as that of the LFS book. If you found LFS
useful, you should also like this!

Since Release 5.0, the BLFS book version matches the LFS book
version. This book may be incompatible with a previous or latter
release of the LFS book.
